The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. Expand to read more Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying. One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time. A natural moisturizer that’s also in our skin A super common, safe, effective and cheap molecule used for more than 50 years Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40% High-glycerin moisturizers are awesome for treating severely dry skin We don't have description for this ingredient yet. A clear, colorless oil-like liquid that makes the skin feel smooth and nice (aka emollient) and it does so without it being greasy. What's more, it can even reduce the heavy, greasy feel in products with high oil content. It's also fast-spreading meaning that it gives the formula a good, nice slip. It absorbs quickly into the skin and helps other ingredients to penetrate quicker and deeper. Thanks to all this, it's one of the most commonly used emollients out there. There is just one little drawback: it has a high comedogenic index (5 out of 5...), so it might clog pores if you're prone to it. It seems to us that squalane is in fashion and there is a reason for it. Chemically speaking, it is a saturated (no double bonds) hydrocarbon (a molecule consisting only of carbon and hydrogen), meaning that it's a nice and stable oily liquid with a long shelf life. It occurs naturally in certain fish and plant oils (e.g. olive), and in the sebum (the oily stuff our skin produces) of the human skin. As f.c. puts it in his awesome blog post, squalane's main things are "emolliency, surface occlusion, and TEWL prevention all with extreme cosmetic elegance". In other words, it's a superb moisturizer that makes your skin nice and smooth, without being heavy or greasy. Another advantage of squalane is that it is pretty much compatible with all skin types and skin conditions. It is excellent for acne-prone skin and safe to use even if you have fungi-related skin issues, like seborrhea or fungal acne. The unsaturated (with double bonds) and hence less stable version of Squalane is Squalene, you can read about it here >> A type of sugar molecule, that has water-binding properties and helps to keep your skin hydrated.
